A mobile terminal comprises: a first frame; a second frame which slides with respect to the first frame; a first horn antenna which is disposed in the first frame; and a second horn antenna which is disposed in the second frame and wirelessly communicates with the first horn antenna. The mobile terminal can omit a physical signal line for transmitting a signal between an electronic component mounted to the first frame and an electronic component mounted to the second frame, and thus can prevent the breakage of the signal line according to sliding movements.
